Tablet support arm structures, systems and associated methods

ABSTRACT

Structures and systems are disclosed for supporting tablets or displays. A core arm extends from a rear end toward a front end, in which the rear end is pivotably mounted either directly to a mount structure, or to an extension arm that is mounted to a mount structure. The front end is pivotably mounted to a front mount structure. The core arm can include a gas spring to provide counterbalance force, and a non-adjustable friction pack element for up/down resistance to support different payloads. The counterbalance can be set within the payload range, while the friction offsets the sink or float that would occur for lighter or heavier payloads. The structures and systems can thus be readily configured for light or heavy configurations, with or without the use of an extension arm, and can conceal cable routing, which is accessible, via snap fit covers, for easy installation and maintenance.

CROSS REFERENCE TO RELATED APPLICATIONS

This Application claims priority to U.S. Provisional App. No. 62/659,358, filed 6 Mar. 2018, and from U.S. Provisional App. No. 62,812,893, filed 1 Mar. 2019, which are each incorporated herein in its entirety by this reference thereto.

FIELD OF THE INVENTION

At least one embodiment of the present invention pertains to tablet support structures, systems and methods of assembly, operation, and service.

BACKGROUND

While mounting arm structures have previously been used to support screens, such as display screens and computer screens, it is often difficult to support different loads, and to position the screen at different heights, within a work environment. As well, it is often difficult to rotate or pivot the supported screen at a desired position.

Furthermore, such screens are often used within a wide variety of work environments, such as within hospitals or other medical or dental facilities, in which cleanliness is important. As it is often required to connect power and/or other cabling to support arms, it is difficult to establish and maintain a sterile environment.

DETAILED DESCRIPTION

References in this description to “an embodiment”, “one embodiment”, or the like, mean that the particular feature, function, structure or characteristic being described is included in at least one embodiment of the present invention. Occurrences of such phrases in this specification do not necessarily all refer to the same embodiment. On the other hand, the embodiments referred to also are not necessarily mutually exclusive.

Various illustrative embodiments will now be described. The following description provides certain specific details for a thorough understanding and enabling description of these examples. One skilled in the relevant technology will understand, however, that some of the disclosed illustrative embodiments may be practiced without many of these details.

Likewise, one skilled in the relevant technology will also understand that some of the embodiments may include many other obvious features not described in detail herein. Additionally, some well-known structures or functions may not be shown or described in detail below, to avoid unnecessarily obscuring the relevant descriptions of the various examples.

The terminology used below is to be interpreted in its broadest reasonable manner, even though it is being used in conjunction with a detailed description of certain specific examples of the embodiments. Indeed, certain terms may even be emphasized below; however, any terminology intended to be interpreted in any restricted manner will be overtly and specifically defined as such in this Detailed Description section.

Introduced here are devices, structures, systems and associated methods for supporting a tablet display within an environment, such as within a hospital or other medical, dental or testing facility. The mounting structures and systems can be mounted in a variety of manners, such as a fixed mounting to a wall, a mounting through an intermediate channel, and/or mounting to stationary or moveable equipment or structures.

Improved support structures and systems are disclosed for installing tablet devices, display screens, flat screen monitors, or medical devices within a wide variety of environments. A core arm extends from a rear end, toward a front end, in which the rear end is configured to be pivotably mounted either directly to a mount structure, or to an extension arm that in turn is mounted to a mount structure. The front end is configured to be pivotably mounted to a front end panel mount structure.

The central core arm can be configured to use a non-adjustable gas spring counterbalance force with a non-adjustable friction pack element for up/down resistance, to support a range of payloads. In some embodiments, the gas spring counterbalance can be set for about the middle of the payload range, wherein friction can be used to offset the sink or float that would otherwise occur for lighter or heavier payloads. With embodiments that include these features, there is relatively more friction in the arm, which results in different user experience and engineering considerations.

As such, some embodiments of the structures and systems can thus be readily configured for light or heavy configurations, with or without the use of an extension arm, and can provide fully concealed cable routing, in which one or more cables are readily accessible, via snap fit covers, for easy installation and maintenance, which can provide a clean structure that can readily be serviced and cleaned as desired.

Some embodiments include joint rotation stop structures that comprise a floating stop key, including stop faces that are movable within a predetermined range, using stop key stop faces that can float. The floating stop key is movable, such as within a track or tunnel that is dynamically formed by the pivoting pieces.

In some embodiments, the joint rotation stop structures can be implemented to limit unwanted rotation of an articulated support arm, such as to reduce the risk of collisions with other objects. In embodiments that are implemented for support arm structures having integrated power and/or signal cables, the joint rotation stop structures can be implemented to prevent such cables from winding up around the joints and breaking.

In an illustrative embodiment of a support arm that includes a core arm, the joint rotation stop structure can be configured to allow the core arm to pivot a full 360 degrees (+/−180 degrees).

FIG. 1 and FIG. 2 show illustrative environments 10,20 in which a tablet arm apparatus and system can be used. FIG. 3 shows an illustrative work environment 30, such as a medical facility, in which the tablet arm apparatus and system can be implemented, such as for any of direct mounting to a wall WL, mounting to a modular wall structure SW, or mounting to a stationary structure SS or to a movable structure MS. While the illustrative work environments 10, 20, 30 are generally related to medical facilities, such as any of hospitals, medical or dental offices, clinics, laboratories, operating rooms, or other diagnostic, treatment, therapy, or recovery areas, the structures, systems and methods disclosed herein can readily be used for a wide variety of other applications.

FIG. 4 is a front view 40 of a tablet, display or screen 52 mounted to an illustrative tablet arm 42, such as with an intermediate mounting frame 50, in which the illustrative tablet arm 42 includes an extension arm 48. In the illustrative embodiment seen in FIG. 4, the intermediate mounting frame 50 can be configured to contain and surround a tablet display device 52, while providing a secure connection to the mounting arm 42. One or more cables 130 (FIG. 8) can be run internally through the support arm structure 42, from the front tablet mount 59 (FIG. 5), i.e., from the tablet 52, to the rear, i.e., mounting end 46, wherein the cabling 130 can be used to transfer power and/or send and receive data. The tablet arm 42 includes a core arm 44 that extends from a front end toward a rear end 46, and is configured to balance a mounted device 52, e.g., a tablet 52, within designed force-to-move limits. In typical embodiments, the core arm 44 is configured with a combination of friction 330 (FIG. 33) and spring forces 326 (FIG. 33), such that the core arm 44 does not require counterbalance adjustment.

FIG. 5 is a rear view 56 of a tablet or screen 52 (FIG. 4) mounted to an illustrative tablet arm 42, e.g., 42 b, such as with an intermediate mounting frame 50, in which the illustrative tablet arm 42 seen in FIG. 5 includes an extension arm 48.

FIG. 6 is a front view 60 of a base configuration of an illustrative tablet arm 42 b having an extension arm 48, which can be implemented for light or heavy applications. The illustrative tablet arm 42 b seen in FIG. 6 can be positioned in a wide variety of positions; for instance:

-   -   the extension arm 48 can be rotated horizontally 70 about the         rear mount 46;     -   the rear end 62 of the core arm 44 can be rotated horizontally         72 about the extension arm 48;     -   the core arm 44 can be rotated vertically 74,76 in relation to         the extension arm 48;     -   the front mount 58 can be rotated generally horizontally 78 from         the front end 64 of the core arm 44;     -   the front mount 58 and attached tablet 52 can be vertically         tilted 82, such as to improve line of sight and/or to reduce         reflection, at a desired elevation; and/or     -   the orientation of the attached tablet display 52 can be rotated         80 (e.g., from landscape to portrait; e.g., 0 degrees plus or         minus a range (such as 0 plus or minus 90 or 135 degrees). In         some embodiments, the orientation 80 can be locked, such as by a         screw or detent.

FIG. 7 is a front view 90 of a base configuration of an illustrative tablet arm 42 a that does not include an extension arm 48, which can be implemented for light or heavy applications. The illustrative tablet arm 42 a seen in FIG. 7 can also be positioned in a variety of positions as desired, such as including any of horizontal rotation 72,78, vertical rotation 74,76, and/or tablet display rotation 80 and/or tilting 82.

FIG. 8 is an expanded assembly view 100 of an illustrative tablet arm 42 b, which includes an extension arm 48. FIG. 32 is an assembled view 300 of an illustrative tablet arm 42 b, which includes an extension arm 48.

As seen in FIG. 8 and FIG. 32, embodiments of the tablet arm 42, e.g., 42 b can be implemented to provide fully concealed routing of cables 130 extending between opposing ends of the tablet arm 42. The cables 32 are accessible via snap fit covers in some embodiments, for easy installation and maintenance. For instance, the core arm 44 seen in FIG. 8 includes a core arm cable cover 108, a rear hinge cable cover 110, a front hinge cable cover 112, and a front hinge seal cable cover 124. As well, the extension arm 48 seen in FIG. 8 includes an extension structure cover 116 and an extension cable cover 118, while the rear mount 42 includes a channel mount cable cover 122.

As such, the exterior as well as the interior of the tablet arms 42 are readily cleanable. As further seen in FIG. 8, some embodiments of the tablet arm 42 include asymmetric construction, whereby one or more cables 130 can be routed 132 to the side of the structural componentry, e.g., core arm structure 102, rear hinge structure 104, and front hinge structure 106, such as to aid in any of manufacturing, maintenance, and cleaning. As further seen in FIG. 8, at the front end of the tablet arm 42, the cable 130 can be routed to avoid kinking or binding, throughout the range of rotation 80 and tilt 82 of the tablet screen 52.

As discussed above, illustrative embodiments of the tablet arm 42 can be positioned in a variety of positions as desired, such as including any of horizontal rotation 120, 122, or 128, vertical rotation 124, 126, and tablet display tilting 130. Some embodiments can be rotated about one or more axes, e.g., pivot axis 154 (FIG. 11), within a defined or predetermined range, such as to allow controlled movement within an environment, while avoiding undesired positioning with respect to the environment or other equipment, and/or to prevent damage or binding to internal cables 130.

Some embodiments of the tablet arms 42 can include one or more stops to limit rotation within range. Some embodiments can include, for example, a stop tooth on the rear hinge structure 104 and a stop tooth on the extension structure 114, which engage at the limit of rotation. These tooth features (or pins, or walls) typically take up space on each component. Therefore, rotation is limited to less than 360 degrees, because the features cannot, by design, overlap and occupy the same space. In some embodiments, such stops can be used, e.g., between a rear channel mount 42 and an extension arm 48, which in some embodiments can readily be configured to provide about +/−90 degrees of rotation 72.

FIG. 9 is an illustrative view of a tablet arm 42 b including a core arm 44 pivotably connected to an extension arm 48, in a first rotated position 138 a. FIG. 10 is an illustrative view of a tablet arm 42 b including a core arm 44 pivotably connected to an extension arm 48, in a second rotated position 138 b. The illustrative extension arm 48 seen in FIG. 9 and FIG. 10 can be rotated 70 from the far left to the far right, while the rear end 62 of the core arm 44 can also be rotated 72 from a far left position to a far right position with respect to the extension arm 48. Similarly, the illustrative front mount 58 (FIG. 7) can also be rotated 78 clockwise or counterclockwise with respect to the front end 64 of the core arm 44. In some embodiments, the rotation 70, 72, and/or 78 can provide a predetermined range, e.g., such as up to 360 degrees (+/−180 degrees) rotation.

As well, in addition to enabling mechanical rotation of one or more components of the tablet arm 42 throughout a wide range of motion, the tablet arm 42 can be configured to provide robust internal routing 132 of cabling 130, without binding or pinching, such as within the predetermined range, which would otherwise limit cable life and/or break the cables 130. For example, in some embodiments, 360 degrees (+/−180 degrees) rotation allows the tablet arm 42 to reach these preferable positions while also limiting over-rotation. Over-rotation is detrimental to cable life, or may even break cables 130.

Some embodiments of the tablet arm 42 include joint rotation stop structures that provide rotation, e.g., rotation 72 of a core arm 44 with respect to an extension arm 48, within such a defined or predetermined range. For instance, some embodiments of the tablet arm 42 can include joint rotation stop structures 140 that include a floating stop key 152, including stop faces 164 (FIG. 13) that are movable within a predetermined range, e.g., stop key stop faces 164 that can float.

FIG. 11 is a partial cutaway view of an illustrative rear hinge structure 104 of a core arm that 44 includes a pivot stop structure 140, which is pivotably connected to an extension arm 48. FIG. 12 is a detailed top partial cutaway view of an illustrative rear hinge structure having a pivot stop structure 140, in which the rear hinge structure 104 is pivotably connected to an extension arm structure 114. FIG. 13 is a detailed top view of an illustrative pivot stop structure 140 for a rear hinge structure 104 of a core arm 44. FIG. 14 is a detailed view of an illustrative rear hinge structure 104 for a core arm 44, wherein the rear hinge structure 104 is configured to include a pivot stop structure 140.

The illustrative pivot stop structure 140 seen in FIGS. 11-14 includes a pivot stop 161, pivot stop disc 150 and a pivot stop floating key 152, such as located within a defined pivot region 166 of a rear hinge structure 104. At the zero degree position shown in FIGS. 11-14, the pivot stop floating key 152 is within a defined range of rotation, and as such, is considered to be a floating key.

As seen in the partial cutaway view of FIG. 11, the pivot stop disc 150 is rotationally fixed to a core arm pivot post 142 about the pivot axis 154, while the pivot stop floating key 152 is captured in the float space 156 (FIG. 12) defined between the pivot stop disc 150 and the rear hinge structure 104. The pivot stop floating key 152 is free to rotate about the pivot axis 154 within the float space 156 between the pivot stop disc 150 and the rear hinge structure 104, within the defined float region 156. The core arm rear pivot post 142 is rotationally fixed 148 to the extension structure 114 about the pivot axis 154, and the pivot stop disc 150 provides stop faces 158 (FIG. 12) for the pivot stop structure 140.

FIG. 15 is an expanded assembly view 170 of an illustrative rear hinge structure 104, an extension arm structure 114, and a pivot stop structure 140, which includes a pivot stop floating key 152 to be located within a pivot region 166 defined within a rear hinge structure 104, a pivot stop disc 150, and a pivot post 142 that extends through the pivot stop disc 150, to be affixed 148 (FIG. 11), such as with respect to landing 171 on the pivot post 142, within pivot hole 146 (FIG. 11) defined through the extension structure, about pivot axis 154.

FIG. 16 is an assembly view 174 of an illustrative rear hinge structure 104, an extension arm structure 114, and a pivot stop structure. FIG. 17 is a top assembly view 178 of an illustrative rear hinge structure 104, an extension arm structure 114, and a pivot stop structure 140. When assembled, the pivot stop disc 150 retains the pivot stop floating key 152 within the pivot region 166 defined within a rear hinge structure 104, to allow rotation of the rear hinge structure 104 with respect to the extension structure 114, within a range of motion.

FIGS. 18 and 19 provide detailed views 180,190 of an illustrative pivot stop structure 140, such as including pivot stop 161, a pivot stop disc 150 and a pivot stop floating key 152, located within a defined pivot region 166 of a rear hinge 104, in which the rear hinge 104 is rotated to a 180 degree counter-clockwise (CCW) position. In the illustrative 180 degree CCW position seen in FIGS. 18 and 19, the floating stop key 152 has been moved, i.e., pushed, by a counter-clockwise pivot rotation motion of the rear hinge 104 with respect to the rest of the assembly. In this position, the floating stop key 152 is in a fully captured position, wherein a set of stop faces 158,162,164, as shown, are active in preventing further counter-clockwise rotation of the rear hinge 170 with respect to the rest of the assembly. Specifically, one of the stop faces 164 of the floating key 152 is captured with respect to a respective stop face 162 of the rear hinge 104, while the opposing stop face 164 of the floating key 152 is captured with respect to a respective stop face 158 of the pivot stop disc 150. In this illustrative case, the rear hinge 170 has been rotated 180 degrees counter-clockwise to a stopped position, with respect to the extension structure 114.

FIG. 20 is an expanded assembly view 200 of an illustrative rear hinge structure 104, an extension arm structure 114, and a pivot stop structure 140, which includes a pivot stop floating key 152 to be located within a pivot region 166 defined within a rear hinge structure 104, a pivot stop disc 150, and a pivot post 142 that extends through the pivot stop disc 150, to be affixed 148 (FIG. 11), such as with respect to landing 171 on the pivot post 142, within pivot hole 146 (FIG. 11) defined through the extension structure, about pivot axis 154.

FIG. 21 is an assembly view 204 of an illustrative rear hinge structure 104, an extension arm structure 114, and a pivot stop structure. FIG. 22 is a top assembly view 208 of an illustrative rear hinge structure 104, an extension arm structure 114, and a pivot stop structure 140, wherein the rear hinge 170 has been rotated 180 degrees counter-clockwise to a stopped position, with respect to the extension structure 114.

In this position, the rear hinge structure 104 is prevented from being rotated further counterclockwise, but can readily be rotated clockwise with respect to the extension structure 114, within the defined range of motion.

FIG. 23 is a first completed assembly view 220 of an illustrative rear hinge structure 104, an extension arm structure 114, and a pivot stop structure 140, wherein the rear hinge structure 104 is rotated 180 degrees counterclockwise, with respect to the extension structure 114. FIG. 24 is a second completed assembly view 230 of an illustrative rear hinge structure 104, an extension arm structure 114, and a pivot stop structure 140, wherein the rear hinge structure 104 is rotated 180 degrees counterclockwise, with respect to the extension structure 114.

FIG. 25 is a detailed top view 240 of an illustrative pivot stop structure 140 for a core arm 44, wherein the rear hinge structure 104 is rotated 180 degrees clockwise (CW) with respect to an extension arm structure 114. FIG. 26 is a partial cutaway view 250 of a tablet arm 42 including a rear hinge structure 104 that includes a pivot stop structure 140 that is pivotably connected to an extension arm structure 114, wherein the rear hinge structure 104 is rotated 180 degrees clockwise with respect to an extension arm structure 114.

FIG. 27 is an expanded assembly view 260 of an illustrative rear hinge structure 104, an extension arm structure 114, and a pivot stop structure 140, wherein the rear hinge structure 104 is rotated 180 degrees clockwise (CW). FIG. 28 is an assembly view 264 of an illustrative rear hinge structure 104, an extension arm structure 114, and a pivot stop structure 140, wherein the rear hinge structure 104 is rotated 180 degrees clockwise. FIG. 29 is a top assembly view 270 of an illustrative rear hinge structure 104, an extension arm structure 114, and a pivot stop structure 140, wherein the rear hinge structure 140 is rotated 180 degrees clockwise.

FIG. 30 is a first completed assembly view 280 of an illustrative rear hinge structure 104, an extension arm structure 114, and a pivot stop structure 140, wherein the rear hinge structure 104 is rotated 180 degrees clockwise with respect to the extension arm structure 114. FIG. 31 is a second completed assembly view 290 of an illustrative rear hinge structure 104, an extension arm structure 114, and a pivot stop structure 140, wherein the rear hinge structure 104 is rotated 180 degrees clockwise with respect to the extension arm structure 114. The illustrative joint rotation stop structure 140 includes a pivot stop disc 150 and a pivot stop floating key 152, located within a defined pivot region 166 of a rear hinge 104, in which the pivot stop structure 140 is rotated to a 180 degree clockwise (CW) position.

As discussed above, the illustrative pivot stop structure 140 seen in FIGS. 25 to 31 includes a pivot stop disc 150 and a pivot stop floating key 152, located within a defined pivot region 166 of a rear hinge structure 104, in which the rear hinge structure 104 is rotated to a 180 degree clockwise (CW) position. In the illustrative 180 degree CW position, the floating stop key 152 has been moved, i.e., pushed, by a clockwise pivot rotation motion of the rear hinge structure 104 with respect to the rest of the assembly, i.e., with respect to the extension structure 114. In this position, the floating stop key 152 is in a fully captured position, wherein a set of stop faces, as shown, are active in preventing further clockwise rotation of the rear hinge 104 with respect to the rest of the assembly. In this illustrative case, the rear hinge structure 104 has rotated 180 degrees clockwise to a stopped position, with respect to the extension structure 114.

In the illustrative embodiments of the joint rotation stop structure 140, the floating stop key 152 is movable, such as within a track or tunnel region 156 that is dynamically formed by the pivoting components, i.e., the rear hinge structure 104, the relative position of the pivot stop disc 150, and the movable, i.e., floating stop key 152.

While the illustrative joint rotation stop structures 140 are described with respect to rotation between a core arm 108 and an extension arm 104, the joint rotation stop structures 140 can readily be implemented for other rotatable joints or interfaces, such as between an extension arm 104 and a rear mount 102, or between the front end 110 of a core arm 108 and a connected component, e.g., a front mount 58. As well, the joint rotation stop structures 140 can be configured to be used for other applications, such as for any mechanical pivot or joint having specific rotational requirements and/or that includes cabling that would otherwise be prone to wear or damage.

In some embodiments, the joint rotation stop structures 140 can be implemented to limit unwanted rotation of an articulated support arm 42, such as to reduce the risk of collisions with other objects. In embodiments that are implemented for support arm structures having integrated power and/or signal cables 130, the joint rotation stop structures 140 can be implemented to prevent cables 130 from winding up around the joints, and breaking. In some embodiments, the joint rotation stop structure 140 can be configured to allow the core arm 108 to pivot a full 360 degrees (+/−180 degrees).

The floating stop key 208 introduces stop faces, as shown, which can move within a design range, because the stop key stop faces can float. Essentially, the floating stop key 152 is configured to move within a dynamically formed track or tunnel, e.g. the float region 156, that is created by the pivoting pieces.

Embodiments of the illustrative joint rotation stop structures 140 can therefore be configured to prevent cables 130 from winding up around the joints and breaking. While the joint rotation stop structure 140 can be configured to provide rotational movement within other defined ranges, some current embodiments allow the core arm to pivot a full +/−180 degrees (yielding a defined range of 360 degrees).

While some illustrative embodiments of the tablet arm 42 are specifically configured for use an overbed table, the tablet arm 42 and corresponding defined range of rotation can readily be configured for a wide variety of uses, with one or more design constraints, such as including any of specified ranges of motion, forces to move, mounting type, stationary, mobile operation, and/or mounted devices.

As discussed above, embodiments of the illustrative joint rotation stop structures 140 can be configured to prevent cables 162 from winding up around the joints and breaking, and/or can be configured to limit unwanted rotation, for example to reduce the risk of collisions with other objects.

In an illustrative embodiment, the joint rotation stop structure 140 allows a full 360 degrees (+/−180 degrees) range of rotation, which is often preferred when the main function is to prevent cable winding. In an illustrative embodiment to be used between a rear hinge structure 104 and an extension structure 114, the design rotation range can be defined as: Rotation range=(angle length of path in rear hinge 170)+(angle length of path in the stop disc 150)−2*(angle length of the floating key 152).

In the case of the illustrative configuration disclosed above, the rotation range=(270)+(270)−2*(90)=360 degrees (+/−180 deg). In some embodiments, the rotation range can be set, up to limits of physical possibility, to be more or less than the illustrative rotation range described with respect to the embodiments disclosed above.

For instance, for some embodiments of the tablet arm 42 that do not include an extension structure 114, such as for a direct connection to a wall mount 46, the range of motion can be 180 degrees (+/−90). For such an embodiment, the joint rotation stop structure 140 can be configured with 180 degrees of floating key length, such as by including two floating keys 152 in the assembly 140 (e.g., 90 degrees+90 degrees=180).

FIG. 33 is a partial cutaway view 320 of an adjustable core arm structure 322 for an illustrative tablet arm 42, in which the adjustable core arm structure 322, such as installed within the core arm body structure 325, includes both a gas spring 324, as well as a friction element 330, e.g., a friction pack element, such as integrated with the rear axle 328 and/or the front axle 332, in which the friction element 330 provides resistance and/or torque. As also seen in FIG. 33, the illustrative gas spring 324 is configured in conjunction with a link bar 334, such as extending between link bar pins 336, to form a 4-link parallelogram assembly 340.

FIG. 34 is a schematic diagram 360 that illustrates some of the key design parameters to be considered for different mounted loads for a tablet support arm 42, such as based on a user force required to move a mounted tablet 52 up or down within a range of motion. For example, if too little force is needed to move the mounted tablet 52 up or down from one angle to another, the mounted screen 52 may undesirably sink or float, creating a functional issue. As well, if too much force is needed to move the mounted tablet 52 up or down from one angle to another, such movement may also be undesirable.

The illustrative performance parameters 368 seen in FIG. 34 can take into account one or more factors, such as the mounted load (lbf.) 362, the balance force (lbf.) 364, and the angle (degrees) 366.

For instance, some embodiments of the tablet support arm 42 can be configured to provide acceptable movement performance 368 for an intended load 362, with a combination of precise friction 330 and spring force 326. Some embodiments are configured to provide acceptable movement performance 368, with no counterbalance adjustment, such as by the use of a combination of friction 330 and spring forces 326. Some embodiments are configured to balance a mounted device 52 within designed or specified force-to-move limits. For instance, some embodiments can provide a light arm 42, such as for supporting 2.0 to 4.5 lb. devices 52, while some embodiments are configured to provide a heavy arm 42, such as for supporting 3.5 to 6.0 lb. devices 52.

Theory of “Counterbalance” Design for Tablet Arm.

Illustrative embodiments of the tablet core arm 44 disclosed herein can be configured to use a non-adjustable gas spring counterbalance force with a non-adjustable friction pack element 330 for up/down resistance to support a range of payloads.

In some embodiments, the gas spring counterbalance can be set for about the middle of the payload range, and then the friction can be used to offset the sink or float that would occur for lighter or heavier payloads. With this design there is relatively more friction in the arm, which results in different user experience and engineering considerations. Understanding desirable User Force preferences is a critical design input.

Explanation of User Forces.

In a first theoretical case, it is assumed that there is a mid-range payload, with the support arm 44 perfectly gas spring counterbalanced, and with equal friction resistance 330 up and down. In this case, the amount of force to move the arm up and down is purely friction resistance, and the amount of force required to move the arm up and down is the same.

In one example, the User Force to move up is +2 lb and down is −2 lb. The Differential User Force is then +(+2 lb)+(−2 lb)=0. In this example, the Differential User Force has no bias.

With a payload that weighs 1 lb more than the mid-range, the friction actually holds the arm up. The User Force to move up would be 3 lb and down would be −1 lb. The Differential User Force is +(+3 lb)+(−1 lb)=2 lb. Under these conditions, the user would need 2 lbf more to move up vs. down. Therefore, in this scenario, there is a + (up) bias.

With a payload that weighs 1 lb less than the mid-range, the friction actually holds the arm down. The User Force to move up would be +1 lb and down would be −3 lb. The Differential User Force is +(+1 lb)+(−3 lb)=−2 lb. In this example, the user needs 2 lb more to move down vs. up. There is a − (down) bias.

Note that in the case where friction up and down is perfectly equal, the Differential User Force is simply twice (2×) that of the gas spring counterbalance mismatch, because the friction zero's out in the equation.

The scenario used above to explain user forces is a simplified theoretical situation. In reality, the gas spring counter balance will vary in mismatch over the arm travel. Also, the spring force has a manufacturing tolerance, so the mid-range will be different from arm to arm. The internal friction pack also has a manufacturing tolerance so the resistance will vary from arm to arm, although in a given arm the up/down amount from a given friction pack may generally be the same. In addition, the gas spring 324 has its own linear friction and the pivoting joints of the arm at the axles 328,332, link bar pins 336 (FIG. 33), and to a lesser degree the gas spring pivots 338 (FIG. 33), also have friction with kinematic relationships with arm position. The stack-up of mismatches and tolerances is therefore preferably accounted for in the engineering design.

For “counter balance”, it is a fundamental requirement that the tablet arm 42 must support a mounted payload in any (positionable) static position when the mounted payload, e.g., a tablet display 52, is within the specified product limits. In preferred embodiments, this should be true for all combinations of mismatches and tolerances and at all required vertical positions; the approach is a worst case total stack-up analysis including all element tolerances. For “User Forces”, as with the counter balance analysis, the worst case mismatch and tolerance stack-up is used. However, when analyzing User Differential Force, it is recognized that, for a given tablet support arm 42, the friction is symmetrical up and down at a given height, and therefore the friction tolerance does not influence the Differential force, although it does affect the overall force. It is likewise for the gas spring tolerance. However, the mismatch of all the support forces vs. the perfect balance forces does result in a variation of the differential force to over the arm travel, to a high degree, because of the arm geometry (e.g., friction torque vs. linear force) so the case is not as simple as the idealized case used in the Explanation of User Forces. Calculations for the analysis of arm balance include the requirements below.

User Force Requirements.

A study was performed to learn user preferences that were analyzed to define desirable functional requirements, based on an exemplary design goals. It should be understood that, while the following specifications are generally pertinent to the goals of one or more products, the acceptable and preferred specifications may, and likely would, vary for other products with different payloads, etc. For example, the disclosed design parameters can be scaled “up” for heavier, bulkier, devices, where the specific numbers will be different, and similarly can be scaled down for light and/or compact embodiments.

User Force to Move the Arm UP:

-   -   Feels “good”: +0.5 lbf to +4.5 lbf (most to least desirable)     -   Feels “okay”: +0.5 lbf to +5.5 lbf     -   Feels “bad”: outside the “okay” range.         User Force to Move the Arm DOWN:     -   Feels “good”: −1.0 lbf to −5.5 lbf     -   Feels “okay”: −0.5 lbf to −6.5 lbf     -   Feels “bad”: outside the “okay” range.         User Differential Force:     -   User Differential Force>=0 then +8.5 lbf to 0 lbf (that is If         User Force |UP| is more than or equal to |DOWN|)     -   User Differential Force<0 then 0 lbf to −4.0 lbf (that is If         User Force |UP| is less than |DOWN|)

Different embodiments of the tablet arm 42 are configured to provide controlled and stable movement, through a wide variety of positions, and for a wide variety of mounted devices 52, with or without the inclusion of an extension arm 48, and for mounting to a wide variety of stationary, movable and mobile applications.

For instance, embodiments of the tablet arm 42 a that do not include an extension arm 48 can readily be configured to provide controlled and stable movement, through a wide variety of positions, and for a wide variety of mounted devices 52.

FIG. 77 is a detailed view 610 that shows an illustrative torque insert body 330 in relation to the rear hinge structure 104 of a core arm 44.

FIG. 79 is a side cutaway view 680 of an illustrative torque insert body 330 in relation to the rear hinge structure 104 of a core arm 44.

The illustrative embodiment seen in FIGS. 77 to 79 present details related to counterbalance and friction for the core arm 44. For instance, the end sections 642 of the torque insert body 330 function as the rear axle 328, while the rear hinge structure 104 pivot on the outer diameter surfaces of the torque insert body 330. The middle section of the torque insert body 330 is fixed to the body structure XX of the core arm 44. As such, the friction insert body is driven rotationally, by lever action, when the core arm 44 is moved up or down. The end fitting 644 of the torque insert body 330 remains fixed on the rear hinge structure 104, which pivots concentrically on the torque insert body 330.

FIG. 80 is a top view 700 showing illustrative body structure details of a core arm 44. FIG. 81 is a partial side cutaway view 720 showing illustrative body structure details of a core arm 44. FIG. 82 is a side view 740 showing illustrative body structure details of a core arm 44.

FIG. 87 is a detailed view 870 of an illustrative torque insert for a core arm 44. FIG. 88 is an alternate detailed view 880 of an illustrative torque insert for a core arm 44.

The torque insert body end sections function as a rear axle. The rear hinge of the arm pivots on the outer diameter surfaces of the torque insert body. The torque insert body middle section is fixed to the body structure of the arm. As such, the friction insert body is driven rotationally, by lever action, when the arm is moved up or down. The end fitting remains fixed in the rear hinge, which is configured to pivot concentrically on the torque insert body. The torque insert end fitting is fixed to the rear arm hinge.

In some embodiments, the torque insert contains internal friction elements. A shaft is engaged in the friction elements. The shaft is configured to rotate in the housing only after a specific amount of minimum torque is applied. That is, differential rotation of the housing and end shaft results in pivoting friction at a specific torque between the two. Some of the unique features about the implementation of the torque insert is the design of the housing and end fitting, which allows the housing to also function as an axle, e.g., the rear axle 328, of the support arm 34. The end fitting is held fixed as the housing is rotated, and this results in a specific amount of friction torque in the rear axle joint. In some embodiments, the friction insert is available through Reell Precision Manufacturing Corporation, of St. Paul, Minn.

FIG. 89 shows expanded structural and out cover assembly views 900 for an illustrative embodiment of a tablet arm 42 b that includes a rear extension 48 and a channel mount 46. As seen in FIG. 89, a channel mount structure cover 902 can be mounted on the channel mount structure, while a rear extension pivot post 904 can be used to pivotably mount the extension structure 122 to the channel mount structure 122.

FIG. 90 shows expanded structural and out cover assembly views for an illustrative embodiment of a tablet arm 42 a, without a rear extension 48, having a channel mount 46.

FIG. 91 is a first completed assembly view 960 of an illustrative core arm 44. FIG. 92 is a second completed assembly view 980 of an illustrative core arm 44. FIG. 93 is an expanded assembly view 1000 of an illustrative embodiment of a core arm.

FIG. 94 is a flowchart of an illustrative method 1040 for installing a cable 130 for a tablet arm 42, for either embodiments 42 b that include an extension arm 48, or similarly for embodiments 42 a that do not include an extension arm 48. For instance, during the installation of a tablet arm 42, the user U can attach the rear mount 46, such as to a corresponding channel mount, such that the user U can access the structures of the tablet arm, with the cable covers removed. A wall-channel mounted tablet support arm 42 readily provides access to install 1044 or remove an interconnecting cable 130, when the outer covers are removed.

One or more components can include compliant rubber or polymer seals, such as around the rotating edges of the covers, and/or in relation to the routing of one or more cables. As seen in FIG. 8, a user, such as during manufacturing or on site, can readily install 1044 a cable 130 through a mount arm structure, for either embodiments that include an extension arm 48, as shown, or similarly for embodiments that do not include an extension arm 48.

In the illustrative method 1040 shown in FIG. 94, once the user U can access 1042 to the tablet arm structures, the user can then position 1044 the cable 130 through the structures, such as between the front mount 58, i.e., the tablet end of the support structure, and the rear mount 46, i.e., the mounting end of the support structure.

In some embodiments, the cables 130 can generally pass through the axes of joint rotation (or as near to as possible within other design constraints). In some embodiments, there are no exposed cable service loops, which can keep them clean, out of harm's way, out of patients' (especially children's) reach allowing more effective and safe technology deployment to a broader demographic. In some embodiments, the asymmetrical arrangement of gas spring mechanism 324 (FIG. 33) allows space on “side” to run the cables 130.

In some embodiments, easily attachable/detachable covers allow efficient installation and maintenance. On some embodiments, access and maintenance can be accomplished in a matter of minutes. In contrast, for embodiments of structural arms that have all-internal cabling, the process of installing or replacing cable is so onerous that it is restricted to factory work or hours of field work. Embodiments having an asymmetrical arrangement disclosed herein can effectively isolate the cables 130 from the “works” of the tablet arm 42, so as to minimize their exposure to harm/damage.

In the illustrative method 1040 shown in FIG. 94, once the cable 130 is positioned 144 through the structure, the cable covers can be installed 1046. For instance, for an illustrative embodiment of a tablet arm 42 a that includes an extension arm 48, a user U can sequentially install 1046 the cable mount channel cover 122 (FIG. 8), the extension arm cable cover 118, the rear hinge cable cover 110, the core arm cable cover 108, the front hinge cable cover 112, the front hinge cable cover seal 124, and a cable channel seal 134 (FIG. 8). In some embodiments, one or more components can include compliant rubber or polymer seals, such as around the rotating edges of the covers, and/or in relation to the routing of one or more cables 130. The illustrative method 1040 shown in FIG. 94 can readily be performed during manufacturing or on site. In some current embodiments, the outer covers can snap in place, without fasteners, and can be configured to prevent or resist contamination within the environment in which the support arm is used.

The above description and drawings are illustrative and are not to be construed as limiting. Numerous specific details are described to provide a thorough understanding of the disclosure. However, in certain instances, well-known details are not described in order to avoid obscuring the description. Further, various modifications may be made without deviating from the scope of the embodiments.
